The product surface is then positioned and inspected to ensure it is qualified. After that, the circumferential rib detection assembly 4 is rotated to observe the gap between the circumferential ribs of the product and the detection strip 45. The circumferential ribs are then judged to be qualified based on the detection results. After the inspection is completed, the sliding drill jig 5 is moved to the drilling position and positioned to drill the product's K hole.
